ImGui DirectX12 Kiero Hook

A DirectX 12 hook implementation using ImGui and Kiero. This project allows you to inject custom ImGui interfaces into DirectX 12 applications.

Features

• DirectX 12 Hook implementation
• ImGui integration through Kiero
• Resizable window support
• Fullscreen support
• Minimal performance impact
• Doesn't crash when injected instantly (before window is created)

Requirements

• Windows 10/11
• Visual Studio 2019/2022 or VSCode
• DirectX SDK
• CMake 3.15 or higher
• Git

Building the Project

Using VSCode (Recommended)

1. Install the following extensions:

   • CMake Tools
   • C/C++

2. Clone the repository with submodules:

git clone --recurse-submodules https://github.com/chadlrnsn/ImGui-DirectX-12-Kiero-Hook
cd ImGui-DirectX-12-Kiero-Hook

3. Open the project in VSCode and select a kit using CMake Tools:

   • Visual Studio Build Tools 2019 Release - amd64
   • Visual Studio Build Tools 2022 Release - amd64
   • Clang 16.0.0 x86_64-pc-windows-msvc

4. Select build variant (Debug/Release) and build using CMake Tools

Using Command Line

1. Clone the repository as shown above
2. Build using presets:

# For VS2019 Release
cmake --preset windows-x64-release-2019
cmake --build --preset windows-x64-release-2019

# For VS2019 Debug
cmake --preset windows-x64-debug-2019
cmake --build --preset windows-x64-debug-2019

# For VS2022 Release
cmake --preset windows-x64-release-2022
cmake --build --preset windows-x64-release-2022

# For VS2022 Debug
cmake --preset windows-x64-debug-2022
cmake --build --preset windows-x64-debug-2022

The DLL will be in the bin/{Debug|Release} directory.

[!NOTE] Only x64 builds are supported due to DirectX 12 limitations.

Known Issues

• Debug builds with debug layers enabled might crash
• Minor flickering may occur
• Menu freezes when switching to fullscreen (Alt+Enter) while menu is open

Implementation Details

This project uses:

• Kiero for function hooking
• Dear ImGui for the user interface
• MinHook for API hooking
